Ii'o all whom it may con/sews:

Be it known that we, WILLIAM W. KEEFER, residing stPittsbur and CHARLES E HARDY, residing at Banksvile, in the county of Aikghsny and State 01." Pennsylvania, citizens of the United States, have invented certain new and useful improvements Mine-Cars, cf which the following a spa cation, rsfsrens-e being had therein to the accompanying drawings.

fins object 01 this invention t0 nmvids imdrovsd self-oiling bearings which w-v hiie designed p imarily for the running-gem of a man's-mu may be used in other connections or WhfilGVBZ' such bearings are required.

further object is to improve the general csnstfuction of mine-car running-gem and to provide for securing and bracing the same t0 the est-body that the miles are held. ps1- nmnentiy and sssursiy .11 prepsr positiim with .rslmtisn ts stash other sad to ths body.

We ciaina- 1. A car part or member cohsisting of a sill adapted to ext-rind longitudinally of a carbody and formed with a plurality of-transverse sjournalsbearings and with oil charnhers beneath the bearings. 4

2. A car part or membenconsisting of a sill termed with depending oil-chambers, each chamber eing open to admit a journal, and, a earring u'rface in the upper portion of each, 0 amber. I l

3. A. car partor member consisting of a sill formed with depending oil-chambers, each chamber bein open laterally for the admission of a journa and a bearin in the up: per

' mg isposed transversely of the sill.

4. A car part or member consisting of a sill. formed with depending oil-chambers, each chamber havin journal-openings at opposits sides and a hearing-surface between and in line with the openings.

A car 1 art or member consisting of a sill formed with a d ep ending oil-chamb er open laterally for the admission of a journal, a hearing suriace in the upper portion of the mountings to the draw-bar.

ortion of each chamber, said hearimg be saacvi chamber and disposed transversely of the sill, the sill having a ring-admitting slot opening downwardly through the bearing and into the chamber.

6. The combination of a csir-body, a pair of sills extending longitudinally of the car at ep' extending from the sills to the car ends, alining bearings carried by the op osite sills, axles journaled 1n the bearings, an Wheels. I

9. The combination of a car-body, a drawbar extending longitudinally thereof, axlemountings, and braces extending from said 10. 'The combination of a car-body, sills extending longitudinally of the car at oppo site sides thereof, axles mounted in the sills, a -draw-bar extending longitudinally of the car, and braces extending from the sills to thedraW-bar. a
